http://opportunities.alumdev.columbia.edu/frederick-griffith-transformation-experiment.php WebIn this paper, I argue that the key to understanding the significance of bacterial transformation - and the scientific legacy of Fred Griffith - rests not only on it initiating a cascade of events leading to molecular genetics but also on its implications for epidemiology based on the biology of host-parasite interactions.

WebFrederick Griffith first discovered the fact that bacteria could transform. He was the first to demonstrate that DNA could be horizontally transferred between organisms of the same generation instead of vertically (from parent to offspring). (2) Web2 days ago · Quick Reference. (1881–1941) British microbiologist. Griffith, who was born at Hale in southern England, has been described variously as a “virtual recluse” or “quiet and retiring.”. He worked as a bacteriologist at the Ministry of Health's pathology laboratory in London and was killed working in his laboratory during an air-raid. freeline organic food b.v
